Second that "All Hail NaZ"
Well - i was able to bend my bars which I shud not be able to and they frame is really wobbly - was partly fixed with glueing in bushings and also some extra washers lol - i just bounce too hard
but the spring is amazing!!! i get height easily - i mean i am not doing loads of fancy tricks - one month on them now and 3 months on the old ones before the gap year but i can easily manage to do easy stuff like ocr, double spring grap, 360,...
but i am also bottoming them out already - so I don't know ur weight but go at least 15-20kg higher - am 66 on the 80's and it is easy for me to bottom them
